Planet Vegeta

Vegeta – The planet Vegeta is seen only briefly in the anime and manga, and there is little information given as to its exact nature. What is known is that Vegeta possesses ten times the gravity of planet Earth. The planet was originally called Planet Plant, and was at this time home to two races: the Tuffles and the Saiyans. The Tuffles were a diminutive race who lacked physical strength and toughness, but were very intelligent and skilled with technology. By contrast, the Saiyans were a very strong and powerful, but primitive race. The Saiyans killed off the Tuffles and took the planet for their own. Frieza soon seized control and used the Saiyans to conquer other worlds. He eventually destroyed it to keep the Super Saiyan of legend from emerging, though it was later restored, and renamed as Planet Tuffle, thanks to Baby's actions in Dragon Ball GT.

Trivia

In the real world, a planet is a celestial body, typically formed during the birth of star and composed of rock or gas left over from that event, that has a fixed orbit around a parent star. Depending on size, a planet can have a variable gravitational effect on other celestial bodies and objects (e.g. other planets, asteroids, comets, etc.).
